SPINDLE RETAINER.

Application mea April 3, 192e. serial No. 99,603.

This invention relates to spindles such as are commonly employed in spinning machines or the like and more particularly to ldevices for retaining such spindles upon their supports.

An object of this invention is to provide an improved device or" the type set forth of such construction and arrangement that it can be easily and quickly moved into and out ot operative position.

A further object is to provide a device of the type set forth which is simple inl the line 3-3 of Fig. 4 and Fig. 4 is a longitudinal sectional view on thevline 4 4 01": Fig. 2.

The particular embodiment ot' this invention which has been chosen for illustration is shonln in connection With a spindle 5 ot ordinary construction rotatably supported on a bolster 6 in the Well known manner. The bolster is provided with a threaded extension 7 by means of which it is mounted on a suitable support 8 toward which it is yieldingly pressed by a coil spring 9 interposed between the support and a nut 1() threaded to the extension.

A simple and easily opera-ted device is provided for normally retaining the spindle in operative position upon the supporting bolster. As illustrated, this device consists of a retainer orv keeper plate 11 having a anged finger 12 adapted to normally cooperate vvith a circular flange 13 formed on the yassociated end of the spindle tor retaining` the letter in position upon the supporting bolster. rlhe retainer is eccentrically movable with relation to the spindie about a center Which is offset With relation to the axis ot' the spindle. Preferabiy this accomplished by loosely pivoting` the retainer on a pivot 14 formed by a pin or lug extending upwardly from a Wear plate 15 or the like clamped against the support 8 by the pressure of the spring 9. The

plate 15 has flanges 16 engaging the shoulders of the support 8 to prevent relative movement therebetween, but obviously other means may be provided for accomplishing the same function. The'pivot pin 14 is received within the otliset opening 17 formed in the retainer'.

'Means are provided for determining the operative; position ot the retainerrso asfto prevent the linger 12 being moved into, contact with the rotary spindle.l As illustrated, this means consists or" a projection or lug 18 formed on the bolster 6 andjvith which the finger V12 is adapted to engage, when in itsoperative spindle retaining position, as shown in Figs. 1 and 2. has an arcuate slot- 19, see Fig. 3, through which the extension 7 of the bolster 6 extends and which permits the eccentric movement ot the .retainer into and out ofspindie retaining position.

The bolster 6 is provided With a slot 2O which cooperates With the p-ivot pin 14 to prevent movement ot the bolster and to maintain the stop 18 in the proper position. Obviously, other means may be used for this purpose. Preferably a fibre Washer 2lv or the like is provided between the bolster 6 and the retainer.

The operative position of the finger 12 is determined by the stop 18 which is so placed that the finger Will not contact with the spindle although it overhangs the spindie flange 13 so as to retain the spindle in position. lVhen it is desired to remove the spindle it is merely necessary to rotate the eecentrically mounted retainer about the oit'- set pivot pin 14 to the position shown in.

Fig. 8 When the spindle can be removed.V

rEhe spring 9 rictionally holdsl the retainer against unintentional movement so that it is yieldingly held in operative or inoperative position.

Although have described a specific embodiment ot this invention various changes.

The retainer 11 additions, omissions and substitutions will Y said bolster, an offset pin about which said retainer is eccentrically movable with relation to said bolster, a stop on said bolster for determining the operative position of said retainer and a slot in said bolster adapt ed to cooperate 'with said pin for holding said stop against movement.

2. v'lhe combination Witli a spindle of a bolster on which said spindle is journaled, a support for said bolster, a spindle retainer including a plate slidably mounted between vsaidbolstei' and saidsupport and provided "ivitli a finger for retaining said spindle on said bolster and a pin about Wliioli vsaid plate is movable in shifting said finger into operative andYV inoperative position.

3. The e inbination With a spindle of a bolster on which said spindle is journaled,

a support for said bolster, a spindle retainer including a plate slidably mounted between said bolster and said support and provided Witlia finger for retaining said spindle on said bolster, a Wear plate adjacent said sup port and provided Witli a pivot pin about retainer including a plate slidably mountedl between said bolster and said support and having an opening adjacent the slot in said bolster, a linger on said plate for retaining said spindle on said bolster, a Wear plate between said retainer and said bolster provided Witli a pivot pin extending throu'gli- Y tlie opening in said plate and engaging the Y slot in said bolster, Caid retainer being movable about said pin in shifting said finger into yoperative or inoperative position and a stop on said bolster for positioning said linger in spindle retaining position.
